Legal ways to move out early in Ontario
Sometimes tenants need to move before the term of the tenancy is over, or without having enough time to give proper notice. To be sure that you will not owe extra rent if you are in this situation, you can:
get your landlord to agree to end your tenancy,
assign or sublet your place to a new tenant,
give notice if your landlord refuses to let you assign, or
get the Landlord and Tenant Board to end your tenancy.
